I believe its asking to find X, Im sorry if Im wrong and its something else, the question confuses me.
1) x = 16
2) x = 16
3) x = 16
X always equals 16
____________________________
EXPLANATION
x/2 - 5 = 3
16/2 - 5 = 3
8 - 5 = 3
3= 3
x/2 = 8
16/2 = 8
8 = 8
x = 16
16 = 16
Marking me brainliest would be much appreciated! Im trying to get on the leaderboard
The correct answer is x = 43
The area of triangle EFG with a base of 2 feet and height of 8 feet is 8 ft².
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of triangle ABC, hence:
18 ft² = (1/2) * 3 * h
h = 12 ft
Let x represent the height of triangle EFG, hence:
x/12 = 2/3
x = 8 feet
Area of EFG = (1/2) * 2 * 8 = 8 ft²
The area of triangle EFG with a base of 2 feet and height of 8 feet is 8 ft².

If they manage to sell 
tickets, they will earn 
dollars. We want this number to be at least 1000, so the inequality would be
In order to solve this for t, you only need to divide both sides by 15:
So, they need to sell at least 67 tickets to have an income of
dollars

The point is how to remove the brackets when a minus sign is on the left hand side. A second problem is how to get all the terms on one side over to the other.
Step One
Remove the brackets on the left side. This is an absolutely necessary step in the rest of your mathematical studies. What was done in this step affects all three terms on the inside of the brackets. Minus signs are real bad things to misuse. Study carefully how to change the signs when multiplying by a minus.
Rule a minus sign outside the brackets, when multiplied by anything inside the brackets, change the <span>sign to the opposite of what it was</span>.
-20 + 4x + 5x^2 = 20 - 7x^2

Before doing the last step, look at the answers. Two of them are 40. That is the answer for 20 and -20 when transferred. It's 40 which is a plus. So you should be transferring from left to right.
Step Two
Transfer from left to right.
-20 + 4x + 5x^2 = 20 - 7x^2 Add 20 to both sides.
4x + 5x^2 = 20 + 20 - 7x^2 Subtract 4x from both sides.
5x^2 = 40 - 7x^2 - 4x Subtract 5x^2 from both sides
0 = 40 - 7x^2 - 5x^2 - 4x
0 = 40 - 12x^2 - 4x Now you have to put them in the right order.
0 = 40 - 4x - 12x^2 <<<<< Answer
